Does the single port of NVR supports 2MP of data?

No, not all NVR's support 2MP cameras, like this one that supports only 1MP (720p):

However, and IMHO, many, if not most new models have at least 2MP support.

Based on the evidence presented thus far, my answer is 'probably'.

Yes.

But first tell us the brand and model# NVR and then we will supply the evidence.

Is it applicable in all cameras and NVR?

No. What if you design a 2MP camera with flash encoding?

In general, a single data port can handle a 2MP/ 1080P camera without problems.  

Particulars impact this, but even a 100 MB/s Fast Ethernet switch has enough capacity to handle multiple 2MP cameras.  A single port can handle a single camera with no issue.

Agreed, but what if it is a 720p NVR?

Then the limitation is something other than the data port, agreed?

Agreed, but it seemed doubtful that he was only intending to know the theorectical bandwidth of the ethernet interface in megapixels.

How about if I increased the resolution of the cameras, will there be issues?

Issues in latency?

At this point, more technical details about the camera type, number of camera, NVR type, viewing clients, and the network are needed.

Giving a general 'yes' or 'no' answer could easily be wrong without knowing these things.

For example, I have 16 channel NVR and I installed variable resolution of cameras:

4-2MP Cameras

5-3MP Cameras

2-1.3MP Cameras

5-5MP cameras

 

will the NVR can handle this cameras?

I understand you don't want to or can't give specifics here, but without knowing the models and types of equipment you're using a general answer isn't helpful and could easily be wrong.

Is there a rule of thumb about this topic?

No, because you're asking very specific performance parameters without specific inputs.

The 'topic' - bandwidth - is indepth.  If anyone gives/uses 'rules of thumb' on this issue, they are setting themselves up for problems.

Resolutions, CODECs, framerates, scene particulars (how much light/complexity) and the network/ hardware used top transport it and record it all greatly impact the answer to your questions.

See: Video Surveillance Bandwidth Guide 2017 for more.

This string is infuriating.  I would assume there is a real question here somewhere. 

Will the cable be plugged in?

Will the cable be properly terminated?

Is the port PoE?

Is the camera PoE?

Will the camera boot and provide images?

Will the NVR provide a usable IP address?

Will the camera accept this address?

How much data can the individual port accept?

How much combined data can the unit process?

How many cameras will be attached?

Does the NVR allow multiple streams?

Does the camera provide multiple streams?

Will multiple streams be used?

Or, the OP could ask "Hey, can a X brand NVR model XXXX support X quantity of X camera at their maximum bitrate/quality?

I am referring to the NVR can handle in terms of resolution of cameras.

If the interface is 100 Mbps you would probably be fine until the fiftieth concurrent client tried to view the camera....

I have a desk I have to take to my daughter at college.

 

Will it fit in my car?

 

I can not tell you the size of desk or make of car, but I need to know if it will fit, which direction or why it wont fit.

We don't know the size of the car, but the desk is 2MP :)

The definitive answer is NO!  It will not work at all, in any way.  Just stop and don't try it. 

If you want to provide me wrong, you will have to provide all the pertinent information we have been asking for.
